半乳糖基转移酶作为可溶性蛋白质存在于从大鼠睾丸网和附睾收集的液体中。该酶在某些方面与大鼠血清半乳糖基转移酶相似，但在热稳定性、Km 和底物特异性方面有所不同。来自不同动物的 RTF 中酶的活性是可变的，并且讨论了这种可变性可能是由于激素影响所致的可能性。附睾液中的酶单位体积活性高于 RTF 中的酶。讨论了该酶可能参与精子表面蛋白糖基化的可能性。
Galactosyltransferase enzyme is present as a soluble protein in fluids collected from the rete testis and from the epididymis of the rat. The enzyme is similar in some respects to rat serum galactosyltransferase, but differs with respect to its heat stability, Km, and substrate specificity. The activity of the enzyme in RTF from different animals is variable, and the possibility that this variability may be due to hormonal influences is discussed. The enzyme found in epididymal fluid has higher activity per unit volume than that in RTF. The possibility that the enzyme may be involved in the glycosylation of the surface proteins of spermatozoa is discussed.
